GMW 16443 Adhesion Performance Requirements for Lightweight Trim and Foam with Adhesive Backing

EUROLAB laboratory provides testing and compliance service within the scope of GMW 16443 standard. This specification covers the adhesion performance requirements of light adhesive-backed flooring or foam bonded to painted or unpainted metal, plastic, or glass. Primary applications are used on the exterior of the vehicle.

Foams can be open or closed cell of varying polymer technologies. Adhesives for these pressure sensitive applications will either carry a release liner or be provided on release liner sheets (for example, adhesive-backed foam strips). The structure can be applied to the component and shipped as an Assembly Part (POA) or delivered as a separate part for installation at a GM Assembly Center.

Typical applications include spacers, door seals, foam seals (e.g. fasteners), under-hood muckets, foam dams (windscreens/Air Intake Panels (AIP)) and general air, dust and water seals such as gaskets and seals.

Type I - An adhesive-backed application that seals and/or mechanically retains over the life of the vehicle. This type of adhesive application is functional before and during installation, or until it is stuck and/or held down mechanically from the installation site.

Type II - Adhesive-backed foam composite that is retained by the adhesive for the life of the vehicle.
